The paths close to my house in Brighton are significantly hilly. A lot so, that among the hardest climbs have names! My favorite/ nemesis is ‘the snake’, so known as as a result of it winds on and on. Simply while you suppose you’ve reached the highest you flip a bend and discover one other lengthy incline!
Alongside being a troublesome exercise, coaching on the hills considerably alters how we run so let’s discover this.
Uphill operating
The vitality value of uphill operating is larger, making it a difficult however probably rewarding kind of coaching. That is largely because of the elevated work of driving the physique up the hill. Because of this, we see a rise in exercise within the quads, calf, glute max and hamstrings throughout the propulsive part of operating.
Uphill operating tends to extend load on the Achilles tendon and Tibia however decreases it on the Patellofemoral Joint. So we might counsel to cut back uphill operating in these with Achilles ache or Medial Tibial Stress Syndrome (MTSS), particularly if painful.
Nevertheless, with Patellofemoral ache, if it’s effectively tolerated by a runner we’d counsel persevering with these uphills runs. They might be a helpful substitute as a high-intensity exercise if sooner operating is painful for the knee (which it may be as peak knee load tends to extend with pace).

Downhill operating
Operating downhill tends to extend patellofemoral joint stress, so if the runner in our instance above is doing hill repeats it might be higher to run up and stroll down. ITBS additionally tends to be aggravated by downhill operating.
Peak Achilles load is diminished operating downhill however with Tibial load there are some conflicting findings within the research. Van Hooren et al’s glorious current paper reported elevated peak Tibial load with downhill operating, whereas Rice et al. (2023) reported decreased Tibial load and prompt operating downhill might scale back threat of of Tibial stress harm.
A key level with each uphill and downhill operating is the person response will differ.
Pace, gradient, step charge and tissue load all work together and are influenced by approach. For instance, a runner aiming to run sooner downhill might enhance stride size and use a low step charge. This might be anticipated to extend muscular calls for throughout load absorption, particularly on the quads and would probably enhance peak load on the knee and Tibia.
Nevertheless, a extra cautious runner aiming to run downhill extra slowly might enhance step charge, taking brief, fast strides to manage the descent. Whereas it will enhance loading cycles it might scale back muscle calls for and cargo on the knee and Tibia, particularly if pace stays low.

Medical utility
As approach will differ it’s greatest to evaluate somebody operating on the hills throughout gait evaluation if that’s a selected aggravating issue for them. Then you possibly can discover methods to assist, corresponding to taking brief, fast steps downhill to cut back knee load.
It’s possible you’ll want to adapt your energy work too if hill operating is the aim. For instance, together with eccentric quads work for downhill and strengthening the glutes and hamstrings for the uphill.
